COTTON-SCRAPER.

Specification of Letters Patent.

Patented Jan. 5, 1915.

Application filed July 10, 1912. Serial No. 708,631.

To all whom it may concern Be it known that we, THOMAS D. FoLsoM andCHARLES WV. FoLsoM, citizens of the United States, residing atClintonville, in the county of Coffee and State of Alabama, haveinvented new and useful Improvements in Cotton-Scrapers, of which thefollowing is a specification.

This invention relates to that class of devices which are known ascotton scrapers and which are used in connection with a plow of the bulltongue or other type for the purpose of cultivating between the rows andfor other purposes.

The invention has for its object to produce a scraper of simple andefficient construction which shall be shaped or set to operate in themost efiicient manner and which shall be so constructed as to retain itsset when submitted to ordinary or even to rough usage.

With these and other ends in view which will readily appear as thenature of the invention is better understood, the same con sists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claim.

In the accompanying drawing has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theclaim may be resorted to when desired.

In the drawing, Figure 1 is a top plan view of a scraper constructed inaccordance with the invention. Fig. 2 is a rear elevation of the same.Fig. 3 is a plan view of the blade seen at an angle to expose the upperrear edge of the same. Fig. 4 is a sectional view taken on the line 4--1 in Fig. 1. Fig. 5 is a sectional view taken on the line 5-5 in Fig. 1.Fig. 6 is a sectional view taken on the line 6-6 in Fig. 1.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The scraper blade, which is an integral forging or casting, may beregarded as comprising a central portion 1 included between the dottedlines acm in Fig. 1, the intermediate portions 2, 2 included between thedotted lines wm and g y, and the wing portions 3 extending beyond thedotted lines y-y. The central portion 1, which has an aperture 4: forthe passage of the bolt or fastening member on which the blade ismounted for operation, is of equal thickness between the lines a2:r;that is to say, the thickness thereof does not vary horizontally betweenthe vertical center and the ends of said center portion as defined bythe lines :c0c, although the center portion, as well as the remainderportion of the blade, is'made of decreasing thickness from the upperedge and downwardly toward the lower edge which constitutes a sharpcutting edge. The maximum thickness of the center portion 1 at the upperedge of said portion may be from a to inch, according to the dimensionsof the blade. The intermediate portions 2, 2 and the wing portions 33diverge rearwardly from the center portion, and the intermediateportions which are defined by the dotted lines w-m and 1 4 are ofgradually decreasing thickness, horizontally, the thickness decreasingfrom to =3 of an inch or from s to l of an inch, according to thedimensions of the blade. The exact dimensions and the exact decrease ofthe thickness of the portions 2, 2 between the lines xa2 and g y may,however, be varied according to circumstances. The wing portions 8, 3are horizontally of the same thick ness throughout between the lines 1 4and the outer extremities of said wing portions. It will be seen that ablade constructed as herein described has a center portion ofcomparatively great thickness which is calculated to resist wear and toprevent accidental displacement or dislocation of the rearwardlydiverging intermediate portion. The thickness of said intermediateportions decreases gradually in an outward direction to the pointsdefined by the lines y-y, thus maintaining great strength and rigidity,although to a gradually decreasing extent, in an outward or rearwarddirection, as the need for resisting ability becomes less pronounced.The wing portions 3 are made of a thickness throughout which issuiiicient to resist wear under any conditions that are apt to beencountered. and said wing portions are at the same time sufficientlylight to enable the blade to be made of relatively light weight and alsoenabling the blade to be manufactured at a reasonable expense.

The improved scraper blade, as will be seen, is extremely simple inconstruction,

throughout, said intermediate portions being horizontally of graduallydecreasing thickness, and said Wing portions being horizontally of equalthickness throughout.

In testimony whereof We affix our signatures in presence of threeWitnesses.
